More hot-rolled strip per order
scalur®’s very tight tolerances fall far below the usual tolerances of hot-rolled strip. The calculation for our micro-alloyed steel S700MC serves as an example. The standardized tolerance thickness for micro-alloyed steel according to DIN EN 10051 amounts to +/- 0.29 mm at an ordered thickness of 2.10 mm. In comparison, the thickness tolerance of scalur® S700MC only amounts to +/- 0.05, thus being much tighter. Accordingly, the ordered thickness is reduced to 1.86 mm when ordering scalur®. This results in 11 percent less weight and a high potential for lightweight construction, especially when using higher strength steel grades. In addition, up to 120 extra band meters can be allocated per order.
Hot-rolled strip for cold-rolled purposes
With scalur®, thyssenkrupp Steel is proud to offer a hot-rolled strip with a homogenous microstructure for high ease of processing. The quality of our first-class hot strip is comparable to that of a cold strip. Yet, scalur® is much more affordable. Our hot strip has very low levels of sulfide inclusions and thus a high degree of sulfidic purity. At the same time, scalur® is very low in profile and suitable for direct processing. Another benefit: scalur®’s consistently high quality leads to a shortened setup time at the production plant and hence to less downtime and an increased production rate.
